My camera box indicates a version 9.3 for PHOTOfunStudio. I'm on a Windows 7 computer. I do not see a 9.3 version for download.
You can update the application directly to the version 9.5 PE which is available on the official website. Keep in mind that PHOTOfunStudio is an app that comes bundled with your device and it's not possible to obtain it from another place, but you can download updates to the application through the official website.
Skip version 9.3 and obtain the latest one through the following link: http://av.jpn.support.panasonic.com/support/global/cs/soft/download/index.html
